Platform

Linux 65fe86937035 5.4.0-73-generic #82-Ubuntu SMP Wed Apr 14 17:39:42 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux`

Description

I'm trying to cross-compile a Rust application that depends on ethers-rs with the help of rust-musl-cross. However, compilation fails and after some debugging, I found ethers-rs to be the one causing the error.

I'm not opening this issue on ethers-rs as that library can be compiled outside rust-musl-cross without issues.

Steps to Reproduce

Create a Dockerfile anywhere with the following content:

FROM messense/rust-musl-cross:x86_64-musl

RUN git clone https://github.com/gakonst/ethers-rs && \
    cd ethers-rs && \
    cargo build

Run:

$ docker build .

Expected Result

Compilation succeeds.

Actual Result

Compilation fails with:

   Compiling ethers-contract-abigen v0.2.2 (/home/rust/src/ethers-rs/ethers-contract/ethers-contract-abigen)
   Compiling ethers-providers v0.2.2 (/home/rust/src/ethers-rs/ethers-providers)
   Compiling ethers-contract-derive v0.2.2 (/home/rust/src/ethers-rs/ethers-contract/ethers-contract-derive)
   Compiling ethers-contract v0.2.2 (/home/rust/src/ethers-rs/ethers-contract)

Might be an upstream rustc issue, see https://github.com/rust-lang/rust/issues/56935 and https://github.com/rust-lang/rust/issues/85386

Thank for the quick reply! Taking a look at the referenced issues now.

Strangely enough, adding the following to my Cargo.toml solves the issue.

openssl = { version = "0.10.34", features = ["vendored"] }

Turns out it's related to OpenSSL.
